Reaction Steps

1.4 ml of ethyl chloroformate are added to a solution of 2.3 g methyl (4,5-dimethyl-2-morpholin-4-ylmethylcyclohexa-1,4-dienyl)methoxyiminoacetate in 25 ml of THF. The mixture is now heated for 20 hours at 70°. After the mixture has been evaporated, the residue is chromatographed on silica gel (ether/hexane 1:2).
